- To all whomit-mayooncern:

. Paste, of which the following is aspecification, reference being had to the accompanying drawings, forming partthereof.

This invention has reference to improvements in containers for semi-fluid {paste adapted for use with brushes and particularly with dental brushes.

One object of the invention is to so construct a container of the nature herein described that the paste may be delivered auto-1 matically and progressively along the brush and that the flow of the paste may be readily out 01f and the paste drawn backward from the outlet by suction.

Another ob'ect of the invention is to so construct a container of this nature that the brush may be guided in its movement relative to the delivery of the paste.

Another object of the invention is to so construct a container of this nature that a receptacle for the brush is provided.

Other objects of the invention will appear from the following description.

The invention consists in the container having the paste receptacle and the plunger having the outlet.

The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.

Figure 1, rep-resents a sectional view as taken on line 11 Fig. 2 illustrating the improved paste receptacle as constructed for use with an ordinary tooth brush. Fig. 2, represents a cross sectional view taken on line 2-2, Fig.1. -Fig. 3, represents a sectional view taken on line 1-1"Fig. 2 illustrating a modified construction of the device.

Fig. 4, represents a view similar to Fig. 3;

showing the brush receptacle telescoped into the paste receptacle. I

Similar characters of reference designate corresponding parts throughout.

As shown in the drawings the paste receptacle 5 is cylindrical in shape and isclosed at one end and open at the other end and has an internal screw thread. The

. plunger '6 is also cylindrical. in shape and has theexterior screw thread 7 adapterhto be'received by the screw thread 016 .thep'aste receptacle .5. Oneend of: this plunger 6 is closed. bythe member 8v having: the orifice 9 which is in registry with the-tubular paste deliveryor mouth piece 10 and extending in lines parallel with-said mouth piece :10. at the inner wall of plunger 6 are'theguides 11, 11 between which the back-Act a brush can be slidably received. -The .outer. open end :ofithe plunger. 6 is cut away aslat'l2-to expose -.to vlew thisend of said mouth piece :10 -so:that:.the, deliverylaof paste from-said mouth piece can be seen.

For use with a brush A having therigid handle B We provide the closure 13 shaped to receive the handle B of the brush and having the enlargement 14 adapted to frictionally engage the exterior of plunger 6 and having the pocket 15 adapted to receive the outer end of the mouth piece 10. For

use with the brush 0 which is adapted by reason of its size or construction to be wholly received by the plunger 6v we provide said plunger'with the closure 16 hinged to the open end thereof and having the lip 17 which may engage exteriorly of said plunger 6 and having the ocket 18 adapted to receive the outer end of the mouth piece 10.

The paste receptacle 5 is filled nearly to its open end with paste P adapted to flow under pressure but not suflicientl fluid to escape between the screw thread s of said receptacle 5 and plunger 6. Said plunger 6 is now screwed into receptacle 5 until its end 8 bears against the body of paste. The brush A or G, as the case may be, is usually in position in said plunger 6, which constitutes a brush rece tacle, and if said brushv be partially with rawn and the plunger 6 be given a artialrotation to screw said plunger fart er into the paste receptacle the end 8 of said plunger will compress the paste P and will force said paste to flow through orifice 9 and the tubular mouth piece 10 and'such flow of paste will continue I in its movement by the guides 11, 11. When sufficient paste has thus been delivered tothe tacle 5 becomes empty it may receive a new I supply of paste.

Having thus described our invention we claim as new and desire to secure by Letters Patent.

1. A container comprising a brush receptacle having brush guiding members and a paste delivery mouth piece, which communicates with the exterior of said brush receptacle, and a paste receptacle adapted to closely fit the exterior of said brush receptacle and to progressively receive said brush receptacle.

2. A paste container comprising a cylindrical paste receptacle having an inner screw thread, a hollow cylindrical brush receptacle having an end wall and an exterior thread adapted to engage with the screw thread of said paste receptacle, said brush receptacle having an orifice through its end wall, a mouthpiece fixed to the Wall of said brush receptacle and receiving from said orifice, and a closure for said brush receptacle.
